Multi-cancer early detection (MCED): An advancement in cancer screening

Detecting cancer early enough can make a difference to increase the chances of successful treatment. Cancer can affect any of us no matter age, gender or race. 1 in 2 women and 1 in 3 men will develop cancer in their lifetime.

Cancer can start in many different parts of the body, like the lungs, colon or stomach. As tumor cells grow, they shed fragments of DNA into the blood known as circulating tumor DNA (ctDNA). These ctDNAs contain evidence of gene alterations and their profiles are often characteristic of the organ from which they originated. Viruses such as Epstein- Barr virus (EBV) are known to be associated with cancer proliferation. After the virus infection, the parts of the viral DNA integrate with the individual’s DNA, making changes to the instructions on cell growth, and paving the potential onset of uncontrolled growth in the body.
